Explanation:
the arrows show the flow of energy; in other words they show who is receiving the energy
The model of the atom which was supported by the gold foil experiment was nuclear model.
Scientists wanted to prove plum pudding model, however, their experiments led to interesting results which made them hypothesize the nuclear model of the atom instead.
Answer:
A.
Explanation:
It is A because the diagram for choice A shows correctly how cellular respiration produces energy and releases carbon dioxide and water as byproducts(CO2). And it also shows how photosynthesis release or produces oxygen gas (O2)
Answer:
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
Explanation:
In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).
A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.
For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have
Phenotype of parent: A short haired male and long haired female
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
Prokaryotic cells also have loose/free/a ring of DNA (not confined to a nucleus) and they can also sometimes have a capsule (slimy outer layer). Also they have slightly smaller ribosomes- 70s instead of 80s.
